Abstract

The invention provides a method, system and device for modifying data in a block chain and a storage medium. The method comprises the steps: initiating whole network voting when a supervision device detects to-be-changed data, determining a first node device responsible for modifying the to-be-changed data according to a voting record, and generating a bifurcation mark, and sending the bifurcation flag, the corrected data corresponding to the to-be-changed data and the block height to the first node equipment. The first node equipment performs rollback on the block chain corresponding to the data to be changed to generate a new block; storing the new block on a block chain corresponding to the to-be-changed data to form a bifurcated chain; and performing rollback on each block of which the block height on the old chain is greater than the block height of the new block in the bifurcated chain, and storing each rollback block on the new chain of the bifurcated chain until the new chain pursues the old chain. And the second node equipment executes the transaction corresponding to the block chain to generate a block, and stores the generated block on the new chain. According to the method and the device, wrong input data can be modified, and data modification is guaranteed to be fair and public.

Description

technical field [0001] The application belongs to the technical field of block chain, and specifically relates to a method, system, device and storage medium for modifying data in block chain. Background technique [0002] The blockchain has the characteristics of decentralization, non-tampering, and traceability. All nodes in the blockchain keep accounts synchronously. For the recorded data, each node can verify each other, so as to ensure that the recorded data is not easy to be tampered with. However, because of the immutable nature of the blockchain, it is difficult to correct the incorrectly entered data when the data in the blockchain is incorrectly entered. Contents of the invention [0003] This application proposes a method, system, device, and storage medium for modifying data in the blockchain. When the supervisory device detects the data to be changed, a node is elected through voting on the entire network, and the node revises the pending change through rollba...
